Compiles AutoCAD slide files listed in an ASCII file into a slide library file

You can construct slide libraries (SLB files) from slide (SLD) files by using the SLIDELIB utility program supplied in the AutoCAD support directory. The following operating system command line syntax constructs a slide library:

slidelib library [ < slidelist ]

SLIDELIB reads a list of slide file names. This list is normally supplied by redirecting a list of files (one per line in another file created using a text editor or a user-supplied utility program) to standard input.
The operating system commands shown below will create a slidelist file that can be used with SLIDELIB. All the slide files you want to compile into a slide library should be placed in a single directory. At a DOS prompt (version 5.0 or newer), enter the following:

dir *.sld /b > mylist

This creates the file, mylist, that you can pass to the SLIDELIB utility. You can also create this file with a text editor by listing the slide file names (and paths, if necessary), such as lobby, d:\slides\office, and \aec\slides\stairs. The slide file name, but not the drive and directory information, is saved in the library file. Because only the file name is included, a library can contain slides with the same name from different directories, but AutoCAD can access only one of the slides.

To generate the slide library mlib from mylist, enter the following:

slidelib mlib < mylist

This entry creates the file mlib.slb, which contains the names and definitions of the slides listed in mylist.
Warning: Do not delete your original slides. The SLIDELIB program has no provision for updating a slide library once it is created. If you want to add or delete a slide, update the slidelist file and re-create the library with SLIDELIB. All the original slides must be present in order to do this.
